Abstract: Methods, drilling systems, and computer-readable media for evaluating candidate correctional trajectories for a directional drilling well. If the user wishes to investigate alternatives trajectories or trajectories to get a BHA back to a planned trajectory, the computing system allows the user to enter one or more intermediate targets. The computing system generates drilling parameters for the alternative targets and displays them to the user. The user can adjust parameters and intermediate targets, as well as drilling parameters, to investigate a range of possible solutions before selecting an update to the planned trajectory.

Abstract: Automated control of a drillstring in a borehole, which is not in continuous rotation, the drillstring comprising an angled component (a bent sub or the like) and a downhole means of rotating the bit, such as a motor or turbine, which rotates the bit independently of drillstring rotation. Near the distal end of the drillstring are measurement devices, at least one and in some aspects two or more, which are used to measure the orientation of the drillstring/bent sub/bottomhole assembly/drill bit with respect to a geophysical field of the earth, such as magnetism (magnetic toolface) or gravity (gravitational toolface). These measurement devices may be connected to a communications module which transmits the downhole toolface information to the surface. The drillstring is controlled to provide that based upon the downhole measurements the drilling system drills the borehole in a desired trajectory.
